After retiring from my department, where I spent my last 6 years as the chief firearms instructor, I ran my own firearms training business for 10 more years of being an instructor. What I always told all of my students, in uniform or not, was that the best gun in a gun fight is the one you have with you. If you won't carry your 16 shot, full size semi auto, why then it does you no good when the brown stuff hits the air circulation device. If you will only carry a 5-shot snubby, or a 6-shot 32 Auto then that will have to do. The real question is...will you?
